Experimental Consumer Price Index, Release Date: 2019-03-12

In addition to the official CPIs for All Urban Consumers (CPI-U), the chained CPI for All Urban Consumers (C-CPI-U), and Urban Wage Earners and Clerical Workers (CPI-W), the CPI calculates an experimental price index for Americans 62 years of age and older. There are several limitations in the experimental price index which must be considered and understood by potential users of the data.
